If the interior trim is like the exterior front high gloss kidney grilles, they are painted black, not just black plastic. This means you could use a product called Scratch X by Meguires to polish the scratches out of it. I have used this stuff on bikes, helmets, guitars, phones, cars etc and its done miracles!

Sorry to resurrect this thread. I just picked up my F30 today. The high gloss black trim already has a bunch of micro scratches that are an eyesore in the sun. I'm guessing that the dealer probably used a dry cloth on it when prepping it for delivery. Is Scratch X the best polish to use or is there something else I should use to remove the scratches? Thanks
